  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

Resolved You cannot send emails from Plesk because outbound connections on TCP port 587 is blocked

Hi

In 'Server-Wide Mail Settings' I get the warning:
You cannot send emails from Plesk because outbound connections on TCP port 587 is blocked. Check the firewall settings or contact your hosting provider.
Click to expand...
But 587 TCP outgoing is open:
Code: 
[root@nwave-prd-web05 klowet]# telnet smtp.gmail.com 587
Trying 64.233.166.109...
Connected to smtp.gmail.com.
Escape character is '^]'.
220 smtp.gmail.com ESMTP i2sm19591963wmb.28 - gsmtp
In panel.ini, the default settings are still active, see attachment.
Product version: Plesk Obsidian 18.0.23.4
OS version: CloudLinux 7.7 x86_64
Build date: 2020/02/06 14:00

The error you see in Plesk UI is false-positive, the port is being checked only on installation and then the message is not updated.
We have a bug PPPM-11528 to fix in the future.
 
Hi, I see it's fixed "The check on SMTP ports 25 and 587 can no longer return false-positive results. (PPPM-11528)" in Plesk Obsidian 18.0.25 17 March 2020
But I'm using my server for a couple months and I saw this error today
I have no any problem with sending email from server and also I can connect to and from server using port 25 and 587
I tried to click "recheck" - but no luck

Ubuntu 22.04.4 LTS , Plesk Obsidian 18.0.58 upd 1 (ARM64)

Should I just close it?
